Not a rocket stove but a pretty cool fire pit. There's a commercially available one kind of like this. At about $100.00 and made out of thin metal, it seemed overpriced to me, a guy with plenty of steel around, a welder, and a bit of time. It works really well. Puts out a LOT of heat from a little 10" circle and it does eat pellets at a pretty fast rate of about 6 pounds an hour. You can throw regular wood in there as well and keeps chugging along. No sparks, almost no smoke, and very, very little ash. I like it. The wife misses poking at the fire with a stick.  |

Ha Ha. Fun! I saw a quick clip of a pellet smoker the other day. When I have time, I need to look more into pellets.
$100 does seem a bit much and I would be curious about the durability. Whatever. It's a good time.

Thanks for sharing josjor. I have a couple tanks to cut up and I'll roll the inner sleeve out of 9ga. How critical is the inner/outer spacing at the bottom? Looks like only a 1/8" gap but mine might be much wider
Thanks,
Turtle

Thanks for sharing josjor. I have a couple tanks to cut up and I'll roll the inner sleeve out of 9ga. How critical is the inner/outer spacing at the bottom? Looks like only a 1/8" gap but mine might be much wider Thanks, Turtle The gap between the layers on mine is about an inch or more. On the one I saw on Amazon it looks to be about 1/2". I don't think it's too critical. I just used what I had lying around and really, it took longer to drill the holes than it did to build the rest of it. The holes I drilled are about 3/8", although I did a really quick burn with just a gap between the inner and out sleeve and it worked fine. In other words, I just had the outer piece suspended over the edge of the inner one using some 1/4" nuts as spacers. Worked fine but you didn't get the cool "gas jet" look around the edge. Daryl, just to be clear, these are pellets for heating, not the same ones used in pellet smokers. Heating pellets are around $4.00 for a 40lb bag. Cooking pellets are all hardwoods and closer to $10.00 for 10lb. No way I'd spend that kind of money just for a fire pit in the back yard. |

Got it, thanks. I may try a square burn box and spare the work of building a sleeve; I get 9 gauge drops 4' long from a truck body manufacturer but they are never wider than 6"
I bought a skid of hardwood stove pellets, low ash, cost 5 turtlebuks a bag. Makes no reference to smoker application that I'm aware of so they must not be the "food processing" variety

The food ones are 100% woods used for smoking (hickory, mesquite, pecan, etc.). The heating stove ones are usually leftovers from saw mills so pine, fir, etc. In my part of the country there has been a lot of pine beetle kill off of trees so that's what they are using for pellets.

It's like a scaled-up version of those classic little top-lit updraft (TLUD) camping-stoves: the kind you can make from tin cans or buy cheaply on ebay or expensively elsewhere, e.g. www.ebay.co.uk/itm/361544412126www.ebay.co.uk/itm/331844189541wildstoves.co.uk/product/wild-woodgas-mkiit/For something as wide as 10" across, I'd consider having some secondary air going through a tube up the middle as well as the sleeve around the outside. I reckon the way to get the primary/secondary balance right would be by keeping the outer air-jacket reasonably broad but experimenting with the size and number of the holes where the secondary air goes into the woodgas near the top. (You could control it from the bottom but then the velocity of the air-jets would probably be lower.) |
